JP-A-11-300235

  In the above-mentioned conventional garbage processing machine, for example, hot air is blown out from the center and is sucked in from the outer peripheral side, and both the hot air blowout portion 79 and the hot air suction portion 80 are positioned below the upper end surface 50a of the kitchen garbage storage container. While it is circulating, there is a great merit in that hot air is blown to the garbage in the garbage storage container 50, but the following problems are likely to occur on the suction side.

  For example, in the state of the dried garbage in which the drying process has been performed and the water content has been reduced, the dried garbage rises in the kitchen garbage storage container 50, passes through the heater cover 78, and is clogged in the suction passage on the way, thereby deteriorating the drying efficiency. Was.

  Furthermore, when the kitchen garbage is fully filled with the kitchen garbage storage container 50, both the hot-air blowing section 79 and the hot-air suction section 80 are often closed, and the dry garbage is more likely to enter the suction path than in the above-described state. This led to deterioration of drying efficiency due to clogging of garbage.

  In addition, there has been a problem that a failure is likely to occur due to an abnormal temperature rise due to clogging of dust.

  The present invention has been made to solve the above problems, and has a main body case of a kitchen waste treatment machine, a main body lid that is openably and closably disposed on an upper portion of the main body case, and a hot air blower attached to an inner surface of the main body lid.

Together is located below the the hot air Komiguchi for flowing garbage trash container upper surface, the hot air suction hole is obtained by a configuration in which is positioned on the upper side with respect to garbage waste container upper face.

  As described above, according to the present invention, the hot air easily flows to the bottom of the kitchen garbage storage container, and furthermore, the hot air easily flows to the inside of the kitchen garbage in the kitchen garbage storage container. As a result, the drying efficiency is improved and the drying time can be shortened and the electricity bill can be saved.

  In addition, even if dry garbage soars up, not only does it become difficult to clog the garbage by increasing the distance to the hot air suction hole, but even if a large amount of kitchen garbage is thrown in at once, It is difficult to clog the garbage.

  For these reasons, factors that hinder circulation of hot air are reduced, and drying efficiency can be increased. In addition, it is possible to reduce troubles and the like caused by abnormal temperature rise due to clogging of dust in the hot air circulation path.

  A protruding wall 11g is provided in the inner lid 11 between the hot air suction hole 11f and the hot air suction portion 11c within a range that does not block the ventilation path. In a normal use state, the protruding wall 11g sucks dry dust. It works to prevent inflow into the mouth channel. In addition, the protrusion 11g also functions to prevent spillage of dry dust caused by opening and closing of the main body cover 2.

  The kitchen garbage container 4 is designed to be filled with 75 to 80% of the total volume of the kitchen garbage storage container 4 in a full amount, and is fixed between the upper surface of the kitchen garbage and the inner lid 11. Is formed, the distance from the garbage is increased, and the hot air inlet 11k and the hot air suction hole 11f are not blocked.

  The hot air blowing port 11k is located below the upper end surface 4a of the kitchen garbage storage container 4 and faces the kitchen garbage storage container 4, so that the hot air can easily flow to the bottom of the kitchen garbage storage container 4, and furthermore, the kitchen garbage storage. The hot air is also made to flow easily into the kitchen waste in the container 4.

  In addition, since the hot air suction hole 11f is positioned above the upper end surface 4a of the kitchen refuse storage container 4, the suction of dry garbage from the hot air suction hole 11f is reduced, and a large amount of kitchen garbage is removed. Even when the hot air is introduced into the storage container 4, the hot air suction hole 11f is not directly closed.

  Next, when the power is turned on, the heating means 14 in the hot air circulating air path case 12 and the catalyst heating heater in the catalyst deodorizing device 17 are heated, and the fan motor 15b of the blowing means 15 is driven to drive the circulation fan 15a. And the exhaust suction fan 18 rotates. The wind generated by the circulation fan 15a rises as indicated by the arrow in the hot air passage 12b to become hot air while passing around the heating means 14, and then further rises from the hot air outlet 12d to the periphery of the inner lid 11 of the main body cover 2. After passing through the hot air blowing portion 11b opened to the side wall 11a, it is guided by the cover guide 11d, flows through the hot air blowing hole 11e of the inner lid 11, and flows into the kitchen garbage storage container 4 from the hot air blowing port 11k through the hot air passage 23. The kitchen garbage in the kitchen garbage storage container 4 is heated and dried by the hot air, stirred by the rotary stirring blade 6, further crushed in cooperation with the fixed blade 5, and reduced.

  At this time, one of the rotary stirring blades 6 is set up along the inner side surface of the kitchen garbage storage container 4 and close to the height (1/2 h) of the kitchen garbage storage container 4. Therefore, the garbage attached to the inner side surface of the garbage storage container 4 is removed by the rising portion of the rotary stirring blade 6, and the upper portion of the garbage storage container 4 is rapidly stirred by the rising portion. This increases the stirring efficiency.

  Further, since the fixed blade 5 and the rotary stirring blade 6 are located in the hot air passage 23 in the kitchen waste storage container 4, the kitchen waste is crushed by the cooperation of the fixed blade 5 and the rotary stirring blade 6, and condensed and reduced. In the process, the hot air that has flowed into the kitchen garbage storage container 4 from the hot air blowing port 11k through the hot air blowing hole 11e is efficiently blown through the hot air passage 23 to the cooperative portion between the fixed blade 5 and the rotary stirring blade 6, so that the kitchen garbage is removed. The drying efficiency is improved.

  In addition, when the rotary stirring blade 6 is higher than about half the height (1 / 2h) of the kitchen garbage storage container 4, a load is applied to the electric motor 9 for driving the same, and the rotational torque must be increased. Not preferred.

  After that, the hot air containing the odor rises in the kitchen garbage storage container 4 and is sucked into the upper surface of the inner lid 11 from the hot air suction hole 11f of the inner lid 11, and further, climbs over the protruding wall 11g and reaches the hot air suction part 11c. The air flows into the hot air passage 12c from the hot air intake port 12e of the hot air circulation case 12 as shown by the arrow, and flows out of the communication port 13 again into the hot air passage 12b by the circulation fan 15a. Thereafter, the hot air circulation cycle is repeated to heat, dry, and reduce the kitchen waste in the kitchen waste storage container 4.

  On the other hand, a part of the hot air blown out by the circulation fan 15a of the blowing means 15 passes through the gap between the metal case 14a and the case component 12g, the hot air branch 16 and the branch pipe 16a from near the entrance of the hot air outlet 12d. Then, the air is deodorized and discharged to the outside of the main body case 1 through the exhaust port 22 by the exhaust suction fan 18.

  As described above, according to the present embodiment, a certain space is formed between the upper surface of the kitchen garbage and the inner lid 11, the distance to the kitchen garbage is increased, and the hot air blowing port 11k and the hot air suction hole 11f are formed. Will not be blocked. Further, since the hot air blowing port 11k is located below the upper end face 4a of the kitchen garbage storage container 4 and faces the kitchen garbage storage container 4, the hot air can easily flow to the bottom surface of the kitchen garbage storage container 4. The hot air easily flows into the kitchen waste inside the kitchen waste storage container 4.

  In addition, since the hot air suction hole 11f is positioned above the upper end surface 4a of the kitchen refuse storage container 4, the suction of dry garbage from the hot air suction hole 11f is reduced, and a large amount of kitchen garbage is removed. Even when the hot air is introduced into the storage container 4, the hot air suction hole 11f is not directly closed. As a result, factors that hinder the circulation of the hot air are reduced, and the drying efficiency can be increased, and failures due to abnormal temperature rise due to clogging of dust in the hot air circulation path can be reduced.
